Abstract: PURPOSE:To provide an excellent stretch characteristic for a cable by coating a composition in which a kind of filler among magnesium silicate, calcium carbonate, water bearing silicic acid of standard particle size of 100mmu or less is mixed to tetrafluoroethylene-propylene system copolymer. CONSTITUTION:One of fillers such as magnesium silicate, calcium carbonate, water bearing silicic acid of standard particle size of 100mmu or less is mixed to prevent inhomogeneous coating during the bridging of a can. 10 to 80 pts.wt. of these fillers are mixed to 100 pts.wt. of tetrafluoroethylene-propylene system copolymer. If it is less than 10 pts.wt., inhomogeneity cannot be effectively corrected, while if it is more than 80 weight part, coating stretch is deteriorated. The composition is coated extrusive on a conductor or on the periphery of a cable, and then can-bridged, organic peroxide or aminos being added thereto as a bridging agent in the composition. Inhomogeneity during can-bridging can thus be prevented and the excellent stretch characteristic can be obtained.

Title: Semiconductor device and manufacture thereof
Inventor: KAWANAKA SHIGERU
IPC: H01L21/336
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate such adverse effects on SOI(silicon on insulator) elements as parasitic capacitances induced by providing contacts at source and drain regions and body regions which are held between embedded oxide films for these regions, and increase in the leakage current.

Title: Transmitting device for rotation
Inventor: WATANABE YUICHI
IPC: H02K7/10
Filed: 1991-10-02
Abstract: PURPOSE:To enable the forward and reverse rotation of a power source to be transmitted to a driven body easily and securely merely by inserting the output shaft of a drive source by providing one-way clutches, which are coupled to the driving source and transmit only the reverse rotation with each other, inside the common outer ring fixed to the driven body CONSTITUTION:In a one-way clutch, the roller 43 is energized at all times in the direction of an arrow a by a spring 42, and when the shaft 50 is inserted into the hollow part of a protective ring 40, the periphery seeks to slide on the exposed part of the roller 43. Now, when the shaft 50 rotates in the direction of an arrow a, the roller 43 rolling on this shifts in the direction of an arrow a inside the protective ring 40 while rotating on its own axis in the direction of an arrow c, and reaches the deepest part of a recess 36. Since d>g1 in the shallowest part of the recess 36, the roller 43 can not shift more than it, and stops in that position, and is retained in wedge shape between the outer ring 33 and the shaft 50. Therefore, the shaft 50, the roller 43, and the outer ring 33 are coupled integrally. And the outer ring 33 rotates in the same direction as the shaft 50, accordingly, in the direction of an arrow a.

Title: Copying device
Inventor: MIMURA YOSHIYUKI
IPC: G03G15/08
Filed: 1984-12-03
Abstract: PURPOSE:To prevent the electric charge attenuation of a latent image and improve the reproducibility and gradation characteristic of fine lines by passing a toner image through the inside of an oscillating electric field formed between a correction electrode connected to an AC bias source and an electric charge holding body. CONSTITUTION:The toner image formed by a developing device 6 on a photosensitive drum 1 passes through the inside of the oscillating electric field formed between the correction electrode 11 which is connected with a bias power source 12 and is impressed with an AC bias or the bias superposed with the AC and DC and the drum 1. The force to attract the respective toner particles to the drum 1 side or to repulse the same from the drum side is then acted on the toner particles by the oscillating electric field. The toner particles sticking to the non-image part or the non-image part side of an image edge are detached respectively from the surface of the drum and migrate to the electrode 11 side or the image part side. The fine line reproducibility and gradation characteristic are thus improved.

Title: Power supply device
Inventor: SUZUKI SHIGESADA
IPC: H02M7/537
Filed: 1991-10-02
Abstract: PURPOSE:To provide a power supply device which can prevent higher harmonics from being generated, is small and cheap, and has improved reliability by detecting currents which flow to the load side when an activation signal is stopped and controlling switching elements. CONSTITUTION:An inverter circuit 34 has a switching transistor Tr44 connected by providing the primary coil 45a of a transformer 45 between the output terminals of an activation signal circuit 33. Pulsating voltage is applied to the switching transistor Tr44 to issue an activation signal to the on/off control terminal of the switching transistor Tr44 when an AC input power source 30 has low voltage in order to perform the switching of the switching transistor Tr44. When the power source reaches a specified electric potential, the activation signal generation circuit 33 stops the activation signal to turn off the switching transistor Tr44. Even after the activation signal has been stopped, feedback from a current transformer 46 causes switching operation to continue, resulting in self-oscillation operation. This constitution reduces base currents supplied to the switching transistor Tr44 and also reduces the power consumption of an activation resistance 42 and the generation of higher harmonics. It also allows a lighting device which is cheap and small and improves reliability.

Filed: 1991-10-02
Abstract: PURPOSE:To eliminate the measuring error caused by the fluctuation of the inclination of a measuring surface when the thicknesses and the like of an applied film which coat the metal are measured by a Compton scattering X-ray method. CONSTITUTION:A pair of X-ray generating sources 1 and 2 are provided at the symmetrical positions to each other with respect to the normal line at a measuring point O of a measuring surface 21 in this apparatus. A pair of the X-ray generating sources 1 and 2 are positioned on a plane (paper surface) including the predicted maximum slant angle alpha of the measuring surface, and X rays are emitted on the measuring point O by using this apparatus. Even if the optical path length of one incident X rays passing the applied film is changed due to the fluctuation alpha of the inclination of the measuring surface, the optical path length of the other incident X rays passing the applied film is also changed. The lengths are changed so that the changes of the optical path lengths are offset to each other. Therefore, the measuring error is eliminated.
